Inhibitory Control, Conduct Problems, and Callous Unemotional Traits in Children with ADHD and Typically Developing Children.

Compared children with CP/ADHD, CPCU/ADHD, ADHD-only, and controls on two measures of inhibitory control: a Simon/flanker task that measured response selection and a stop signal task that measured response inhibition. Results showed: (a) ADHD was associated with both measures of inhibitory control; (b) control children had better overall performance and ADHD-only had worse response selection than the CP groups; and (c) children with CPCU/ADHD had better response inhibition than children with ADHD-only or CP/ADHD. Results suggest inhibitory control dysfunction is associated with ADHD rather than CP and that response inhibition dysfunction distinguishes children with CP/ADHD from children with CPCU/ADHD.

Beyond the Label: Asexual Identity Among Individuals on the High-Functioning Autism Spectrum.

Researchers have suggested that asexuality, which has been conceptualized traditionally as a persistent lack of sexual attraction to others, may be more common among individuals with autism spectrum disorder than in the neurotypical population. However, no studies to date have considered how these individuals understand and conceptualize their sexual identity. The aim of this study was to provide a more nuanced understanding of asexuality among individuals with high-functioning autism spectrum disorder (HF-ASD) than has been done in the past. Individuals with ASD, 21-72 years old (M = 34.04 years, SD = 10.53), were recruited from online communities that serve adults with ASD and Amazon's Mechanical Turk to complete an online survey of sexual and gender identity. Overall, 17 (5.1%) participants who met study criteria (N = 332) self-identified as asexual. However, 9 of the 17 people identifying as asexual expressed at least some sexual attraction to others. In addition, based on open-ended responses, some participants linked their asexual identity more with a lack of desire or perceived skill to engage in interpersonal relations than a lack of sexual attraction. Results suggest that researchers should be cautious in attributing higher rates of asexuality among individuals with ASD than in the general population to a narrow explanation and that both researchers and professionals working with individuals with ASD should consider multiple questions or approaches to accurately assess sexual identity.

Challenging stereotypes: sexual functioning of single adults with high functioning autism spectrum disorder.

This study examined the sexual functioning of single adults (61 men, 68 women) with high functioning autism and Asperger syndrome living in the community with and without prior relationship experience. Participants completed an on-line questionnaire assessing autism symptoms, psychological functioning, and various aspects of sexual functioning. In general participants reported positive sexual functioning. Participants without prior relationship experience were significantly younger and more likely to be male and identify as heterosexual. They reported significantly higher sexual anxiety, lower sexual arousability, lower dyadic desire, and fewer positive sexual cognitions. The men reported better sexual function than did the women in a number of areas. These results counter negative societal perceptions about the sexuality of high functioning individuals on the autism spectrum.

Brief report: Stony Brook Guidelines on the ethics of the care of people with autism and their families.

The increased prevalence of autism spectrum disorders (ASD), with associated societal and clinical impacts, calls for a broad community-based dialogue on treatment related ethical and social issues. The Stony Brook Guidelines, based on a community dialogue process with affected individuals, families and professionals, identify and discuss the following topics: treatment goals and happiness, distributive justice, managing the hopes for a cure, sibling responsibilities, intimacy and sex, diagnostic ethics, and research ethics. Our guidelines, based not on "top-down" imposition of professional expertise but rather on "bottom-up" grass roots attention to the voices of affected individuals and families speaking from experience, can inform clinical practice and are also meaningful for the wider social conversation emerging over the treatment of individuals with ASD.

Sexual well-being of a community sample of high-functioning adults on the autism spectrum who have been in a romantic relationship.

This study explored factors (gender, age, relationship status, symptomatology) associated with the sexual well-being of 141 (56 men and 85 women) adults with high-functioning autism and Asperger syndrome (HFA/AS) living in the community. Participants completed an online survey consisting of a measure of autistic symptoms as well as measures of dyadic and solitary sexual well-being. Canonical correlation analyses showed that participants who were currently in a romantic relationship reported more frequent dyadic affectionate and genital activity and greater sexual assertiveness and sexual satisfaction, pointing to the importance of context in an active sex life. After controlling for the first variate, men and individuals with less autism symptomatology, particularly in the social and communication domains, generally reported significantly greater dyadic sexual well-being, including greater sexual satisfaction, assertiveness, arousability, and desire and lower sexual anxiety and fewer sexual problems. Men also reported better solitary sexual well-being, including more sexual thoughts, more sexual desire, and more frequent solitary sexual activity; however, they had lower sexual knowledge. These results highlight the importance for research and sexuality education with individuals with HFA/AS to conceptualize sexual well-being as a multidimensional construct consisting of both dyadic and solitary aspects.

Behavioral profiles and symptoms of autism in CHARGE syndrome: preliminary Canadian epidemiological data.

Individuals with CHARGE syndrome were identified through the Canadian Pediatric Surveillance Program (CPSP). From this population-based cohort (n=78), we present data on developmental and behavioral characteristics for the first 13 individuals (eight males, five females) for whom assessments are complete. Standardized parent questionnaires on development and behavior were followed by a structured telephone interview, with a specific emphasis on symptoms of autistic spectrum disorder (ASD). Preliminary results confirm that individuals with CHARGE syndrome have relatively low adaptive behavior skills, motor impairments being particularly significant. Most individuals did not present with significant behavior problems; however, evidence of ASD symptoms was judged to be moderate to strong in six of the ten children who were above the age of 4-5 years. Results are discussed with reference to the challenges inherent in the diagnosis of autism in individuals with sensory impairments, and to the implications for understanding the etiology of CHARGE syndrome and of ASD.

A review of the validity of laboratory cognitive tasks used to assess symptoms of ADHD.

Reviewed the validity of frequently used laboratory assessment measures of ADHD symptoms using research published since 1991. Emphasized examining the validity of the tasks as they are commonly used by clinicians and researchers. Tasks evaluated included the Continuous Performance Test (CPT) and the Gordon Diagnostic System (GDS), the Children's Checking Task (CCT), Delay of Gratification Tasks, the Choice-Delay Task, (C-DT), and the Stop Signal Task (SST). Results showed that the CPT, C-DT, and the SST had the most support, yet further efforts to evaluate the validity of these measures are needed before they can be used for more than experimental purposes.

Food for thought: Will adolescent girls with eating disorders self-monitor in a CBT group?

This study of a Cognitive Behavior Therapy group examined the process of self-monitoring by adolescent females with eating disorders in group treatment. Five females, aged 17-18 with Anorexia Nervosa (n = 2) and Bulimia Nervosa (n = 3), participated in an 8-week treatment group. Self-monitoring occurred on 50% of the days and was highest during the first 3 weeks of treatment. Commitment to monitoring was related to the girls' self-reported readiness to change. Girls with Anorexia self-monitored as frequently as those with Bulimia. The clinical usefulness of self-monitoring with adolescents is discussed.

The development of selective inhibitory control across the life span.

A modification of the stop-signal task was used to investigate the development of selective inhibitory control. A group of 317 participants, age 6 to 82 years, performed a visual choice reaction time (go) task and attempted to selectively inhibit their response to the go task when hearing one of two randomly presented tones (1000 Hz, 250 Hz), each presented on 20% of trials. Measures of response execution and inhibition were assessed by using reaction times to the go signal (GoRT) and stop signal (SSRT), respectively. Results indicated that SSRT gets faster with increasing age throughout childhood, with pronounced slowing in older adulthood. In addition, strong evidence was obtained for age-related speeding in GoRT throughout childhood, with marked slowing throughout adulthood. Subsequent hierarchical regression analyses illustrated that the age-related changes in selective inhibitory control could not be explained simply by overall slowing or speeding of responses. Findings are discussed in regard to the decay and maturation of selective inhibitory control across the life span.
